CORALS - Coggle Diagram
CORALS
base of the food chains
huge consequences for those that live and feed on coral
eventual lag effects on the rest of the food chain
the degree of dependancy leads to huge ramifications
very dependant on water temp
as global temps are changing, patterns will change
colour dissapears, bleaching
when coral dies, erodes mcuh faster
coral may be able to adapt and evolve to grow in hot waters
large colonies of billions of organisms, great diversity
contains over 25% of all ocean's species yet makes up < 1% of ocean
broadcast spawning
coral release egg and sperm which float to the surface and breaks down
as all colonies release - mix up creating new species
overfishing, coastal development, population pressure
8.6 GT of green house gasses per year
70-90% of coral lost on the reef
due to extreme el nino event
ocean's trapping heat and this is increasing each day
